Hi malware fighters,
If your drivers are not producing problems, because some malware coorupted these data, there could be a hardware problem. If you are able to run memtest on the motherboard, I would let this program have its way for at least the night with only a memtest program in the form of a supermini Linux (containing just this memory-test program that starts up at once (it does not do nothing else), and you have to run it from a bootable medium.
There are two different versions (developteams split apparently)
, so try either one,
see: http://www.memtest.org/ &
http://www.memtest86.com/.
Also av as a linux distro that runs on windows can deliver us from an emergency, when everything else fails.
